Absolute Maximum Ratings

These are stress ratings only and functional operation

of the device at these ratings or any other above those

indicated in the operation sections of the specifications

below is not implied. Stresses beyond those listed under

absolute maximum ratings may cause permanent damage

to the device. Exposure to any absolute maximum rating

condition for extended periods may affect device reliability

and lifetime.

BST-SW............................................................. -0.3V to 6V

Storage temperature.................................... -65°C to 150°C

Junction temperature................................................. 150°C

Power dissipation ...................................... Internally limited

Lead temperature (soldering, 10 seconds)................ 300°C

ESD rating (HBM – human body model) ....................... 2kV
